Nice, did you used Unity?
EDIT: I just played it, after I've seen the files I realized it's not made in unity. I have a small feedback for you, when I press the arrow keys to move and the jump button at the same time, it character doesn't jump, it is a bit annoying. Also I have to ask you, would you like to join my team? We are currently three colleagues working on a 2D puzzle-platformer, we could use your help.(you can find the game here: https://halfroundgames.itch.io...)
